Adding IPv6 addresses to a domain is usually quite simple. Instead of an A record, you hast have to add an AAAA record to your database that points to an IPv6 address. If you use a configuration tool like Plesk, adding those records might be a little bit more difficult, as Plesk – at least in the version my hoster uses – doesn’t allow me to add AAAA records. So here is a short tutorial how to add an AAAA record.

Plesk manages the DNS records in a database. We first need a way to insert AAAA records in the database. Luckily if this is done, we are almost finished as the script that generates the zone files, doesn’t do a doublecheck at all.

First of all login as root on your box. Then login to your mysql server using the ‘admin’ user:

Downoad the dnsupdate.sh script from parallels website. You now just need to add an entry to your database using a INSERT statement and then run the dnsupdate. I wrote a extremly hackish and dangerous to use script for that:

I don’t remember when I heard of IPv6 the first time. Back then I tried to learn it a little bit but it was quite hard to get a working solution. When Benoit told me about a french ISP that provides native IPv6 connectivity, recently, I got attracted again by the technology. This time I spend much more time in understanding how IPv6 works and must admit that I really love the way it works. In IPv6 every machine get an unique IP address, that can be (under some circumstances that I’ll explain later) reached from every point of the world. Therefore it solves my NAT issues, so that I can access every machine in my local network from a remote host (if I would let the remote host through my firewall). As IPv6 allows autoconf, I don’t even have to configure my machines in the network, I just need to route the prefix and and announce the prefix. And: IPv6 is pretty easy to get.(more…)

When I started blogging, serendipity was my favorite blog system. It was faster and cleaner to me than WordPress. Also WordPress was known for being a insecure at that time.

Well now after 2 years of blogging I took another look at a WordPress and I must admit that I’m impressed by the clean admin interface and all the nice eye-candy. There are also tons of features that I like to use. So that’s why I decided to finally switch over to WordPress. I hope that my rss redirection will work for most of the people. For sure a lot of links on the web will just link into nowhere, but as I guess most of the links out there are not long-living, I frankly don’t care about that (But I care about the feeds, so give me feedback if you encounter problems).

The most notable change is the design. As I do not have the time to port my selfmade s9y design so far, I stick with a standard theme. Personally, I liked the old one more, but I was told by annoyed people, who had to scroll all the way down to the first article, that the big picture at the beginning wasn’t that good at all.
